IMPROVEMENT IN SASH-HOLDERS. 'A

Specification forming part of Letters Patent No. l l3,l1'16,dated March 28, 1871.

State of Pennsylvania, have invented certain' new anduseful Improvements in Sash-Locks; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying draw ings, and to the letters of reference marked thereon, making a part of this specication.

The nature of my invention consists in the construction and arrangement of a double acting reversible sash-lock,77 as will be hereinafter more fully set forth.

In order. to enable others skilled in the art to which my invention appertains to make and use the same, I will' now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure 1 is a side view of the window-frame, showing my lock; and Fig. 2 is a transverse vertical section of the same.

A represents a portion of the window-frame with suitable spaces or grooves in which the sash are to slide up and down. v v

Through a hole in the window-frame is passed from the inside a shaft or spindle, B, having a longitudinal groove, a. On this spindle, in" recesses formed in the frame, are loosely placed two hooks, C C, or, in other words, the spindle passes freely through holes in the hooks. One of these hooks extends upward ,to operate on the top sash, while the other eXtends downward to operate on the lower sash, and both are pressed outward by means of springs D D, one of which is attached to each hook, and bears against the bottom of the recess, as shown in Fig. 2.

In the eye or hole in each of the hooks C, through which the spindle B passes,.is a small lug, i, which passes into the grooves a on the spindle. The two lugs z fi are .so arranged that they will bear one against each, side of the groove in the spindle when the sash are locked. It will then be evident that if lthe spindle Bis rotated or turned slightly to either side one of the hooks will be forced inward far enough to release its sash, while the other will not be operated upon at all, as its lug or cog v3 will by this motion be relieved from its bearing in the groove.

On the outer end of the spindle B are placed two ears, E E, one projecting upward and one downward. By pressing on the upper ear the upper hook is operated, and by pressing on the lower ear the lower hook is operated.

The edges of the two sash are provided with any suitable number of holes for the hooks to enter, so that the sash may be held at any desired height. The holes in the sash where the hooks enter when the sash are closed are so constructed that the sash cannot be raised without operating the lock.

This sash-lock may-be used on either the right or left side of a window, and the two ears on a single rod or spindle avoid all mistakes in working the wrong sash, as is often the case wit-ha single thumb=plate or ear. The groove running the whole ylength of the spindle allows the hooks or levers- O Gto be placed at any point desired. In other words, it can be used for any-size sash-one-inch as well as two-inch.

Having thus fully described my invention,

what Iclaim as new, and desire to secure by Letters Patent, isv The combination of the spindle, grooved its entire length, and the bolts with lugs in i their perforated end or eye, ,said bolts carrying springs in slots near the eyes, and being operated separately by the revolutions in different directions of the shaft, substantially as set forth. v

In testimony that I claim the foregoing I have hereunto set myl hand this 18th day of January, 1881.
